COTTON-LQADING DERRICK.

SPECIFICATION forming part of Letters Patent No. 426,372, dated April 22, 1890. Application filed October 31,1889. Serial No. 328,784. (No model.)

To all whom it may concern:

Be it known that we, ELDON M. FIELD, J ACKPEGGS, and STEVE BASSINGER, citizens of the United States, and residents of Italy, in the county of Ellis and State of Texas, have invented certain new and useful Improvements in Cotton-Loading Derricks; and we do declare the following; to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a perspective view. Fig. 2 is a vertical longitudinal section.

This invention has relation to portable revolving derricks for loading cotton-bales and other heavy articles; and it consists in the construction and novel combination of parts, as hereinafter set forth.

In the accompanying drawings, the letter A designates the base-frame, which is made in barrow form and consists of the longitudinal sills B, the transverse sills O, the uprights D, the longitudinal handle-rails II, above and parallel to the sills B and secured to the uprights D, and the transverse bearing E, connected to the handle-rails. The sills project outward sufficiently to form a secure base for the derrick wherever it'may be placed.

K indicates the mast or upright revolving shaft, which is provided with a lower shoulder at L, which rests in the bearing E, through the opening 6, in which the shaft passes downward to the pivot-bearing in the base, as at The upper portion of the mast is provided with a shoulder at m, above which rises centrally the squared stud n, which is engaged by the central opening or bearing 8 of the cross-head T. This arm-head is formed with a front arm G and a rear arm G, the latter being connected and braced to the mast by the parallel oblique arms H H which extend from the sides of the mast to the end of this arm of the cross-head.

To the front arm G of the cross-head is pivoted the upper pulley]? of the derrick,

the lower or traveling pulley P being connected thereto by the operating-rope R, which passes a turn over the upper pulley P, and then over the upper sheave P in the slot U of the mast, just below its upper shoulder, as shown. Thence the rope passes downward along the mast and around the drum or windlass P which is mounted in bracketbearings Z, secured to the sides of said mast just above its upper shoulder. The front or lifting arm of the crosshead may be elevated,if necessary, by means of washers on the stud n.

The traveling pulley is to be provided with attachment chains or catches, which may be connected to the lower edge of the block.

This derrick is light and is readily transported by hand to the place where the loading is required. Its broad base gives it stability when in position and prevents it from being overturned by the weight of the bale being lifted. When the bale is lifted above the level of the handlebars of the barrow frame, it can be carried around to required position, the derrick-mast turning freely as the bale is moved.

I-Iaving described this invention, What we claim, and desire to secure by Letters Patent, 1s

The portable derrick, comprising the barrow-base having the longitudinal han die-bars, the extended longitudinal and transverse base-sills, and the bearings, the rotary shaft ormast having the slot and sheave, the upper shoulder and upward-projecting stud, the
